  Polysilyldianions — Synthesis and reactivity

  摘要：

  Reaction of alpha,omega-bis[tris(trimethylsilyl)silyl]alkanes with one equivalent of potassium tert-butoxide resulted in clean formation of mono-potassium silyl anions. Addition of another equivalent of the transmetallating agent led to the formation of the di-potassium compounds. Partial hydrolysis of the dipotassium compounds induced an intramolecular reaction yielding a cyclic silyl potassium compound. (C) 1999 Published by Elsevier Science Ltd. All rights reserved.

• Coupling of Disilane and Trisilane Segments Through Zero, One, Two, and Three Disilanyl Bridges in Cyclic and Bicyclic Saturated Carbosilanes

  Several six-membered cyclic and [2.2.2]bicyclic organosilanes with varying proportions of silicon atoms in the bridges have been prepared following a stepwise approach that exploits dianionic polysilanes. Focus in our analysis was placed on the bicyclic compounds which all have silicon atoms at the bridgehead positions. Quantum chemical calculations of these compounds revealed the possibility to enhance

  按照利用阴离子二聚硅烷的逐步方法，已经制备了几种桥中硅原子比例不同的六元环状和[2.2.2]双环有机硅烷。我们的分析重点放在了在桥头位置都具有硅原子的双环化合物上。这些化合物的量子化学计算表明，有可能通过将一个-SiMe 2 SiMe 2-桥中的一个或两个替换为-CH 2 CH 2-桥来增强单个顺式四硅烷四硅烷笼形链段的偶联。紫外吸收光谱显示，当从具有三个-SiMe 2 SiMe 2的双环[2.2.2]辛烷中移出时，最低可见跃迁发生红移–与具有两个或一个这样的桥的桥。但是，这些红移是具有欺骗性的，因为根据TD-DFT计算，最低的垂直激发单峰态没有显示出相同的趋势。尽管如此，由于这些化合物具有（i）极好的结构刚度，（ii）通过其环外三甲基甲硅烷基提供功能化的潜力，并且（iii）随-SiMe 2 SiMe 2-桥的数目显示出电子结构变化，因此它们可能很有趣有待进一步研究：例如，在单分子电子学中。
